Donald Trump’s rally on Tuesday evening in Albuquerque drew hordes of both supporters and protesters — and the demonstrations outside turned violent.

Demonstrators in New Mexico’s largest city “threw burning T-shirts, plastic bottles and other items at police officers, injuring several, and toppled trash cans and barricades,” said an AP report, which described the situation as “one of the presidential campaign year’s more grisly spectacles.”

The city’s police department said it was a “riot” and “faced such an angry crowd that they called in reinforcements from around the state, seeking to double their numbers to counter the protesters, whose numbers swelled beyond 600,” the local newspaper’s report added.
